What are chlorogogen tissues for? what organ in humans has a similar function?

The chloragogen tissue is found in the annelida.

Explanation:

Liver in human has a similar function that of chloragogen in the annelida. This tissue basically located at the heart or the intestinal wall of the annelida. Due to the presence of Chloragosomes, chloragogens are yellowish in colour. They can help in the synthesis of urea in annelids. These cells also store glycogen.  chloragogen can be also known as Y cells.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
